I This invention relates tomachines for use 1n the manufacture of bootsand shoes for shaping the upper materials, aiidlis herein illustrated inits application to a machine 5 of the type shown and described inLetters .to other portions of the shoe} Patent No 1,692,284, grantedvupon my application on November 20, 1928, havin means for molding thetoe of the upper oh the last substantially to the shape desired forthefinished shoe. IIt-is to be understood,

however, that in various novel and useful aspects the invention isnot'limited to machines of that particular type, no r to inachines forshaping an upper over a form of the character. herein illustrated asdistinguished from a different kind torin'suc-h, for example, as a last,v v "i In shaping or molding the toe, of an upper over a form it isimportant that the work be accomplished in such manner. that thematourof the toe will bear the proper relation 7 It is particu larlyimportant, where uppers are provided wi'tl 'tips, that the tip linebelocated at the proper distance trom the end oif thetoe and liesubstant' ally in a plane. extending inproper angular relationto thethroat oij..th e vamp and to. the bottom ofthev shoe. It is alsonecessary ,'tor sa'tis'factory 'results,"that theupperbe shaped smoothlytothe contour of the ormwithoutthe presence'fof wrinkles in any portionthat is visible in the finished shoe. The present invention hasparticularly in view the provision or means for cont-rolling the upperin the upper-shaping 'orino-lding operation in such manner as toaccomplishthe best results in the different respects above mentioned. Tothis end, the invention pjroe vides' a-novel organization includingdevices for the upper. at 'the oppositesides the toe and for thusholding it against undesirable. displacement relatively to v the form inthe nolding operation.- Asvherein illustrated,grippers are prov dedwhich grip the upper at the opposite f ends of the tip seam and aremovable,inwardly toward the form in response; to the pull of the upperthereon as theiipper isshaped abo'utfthe form, the grippersbeingsocontrolled asto niovein predetermined directions unafiected' bythe directions of thetensions arising. in the upper and thus topr'eVehtnncontiolled inovei'nent lengthwiseot the town of-tlieper tionsof the upper which they engage} J'As applied to an organization of thetype shown, for example,'in the aboveinentioned Letters Patent. includinwi )ers which wi e g l P the upper inwardly over the form to mold a thewipers have arrived substantially or approximately atthe end of theirinward wiping movement In this manner effective control of the margin ofthe upper at the 0pposite ends o f/the tip seam is affordedsubstantially throughout the upper-molding operation so that theend-portions'of the tip seam at the opposite sides of the toe will nobe'forced rea-rwardlyfbythe wipers or be otherwise improperlydisplacedbut will be positionediii-thev proper predetermined relation toothe'r, parts of-the shoe. Inthe construction shown the grippers aremounted to" swine; directly toward each otherlaterally 1 1 the. 'i'orin,or in directions substantially perpendicular to the longitudinal medianline of the form, so: that they hold the upper at the ends of the'tip.seam from any shifting movement lengthwise of v the form during themolding.

' In the shaping, anupper over av form there is, ofcourse, a tendencyfor pleats or, wrinkles to form in its inarginal po-rtion as thelatterisfcont acted about theiorm, especially in that part which is to betrimmed "off after the molding. In a further important aspect,

.the invention aims to-preve it excessive or. indue wrinkling. at anypoint, such as might -i.iiter:tere with the" shaping" of the uppersmoothly over the form, and-"co this end the ii'iven'tion provides'novelmeans -lorcontrol ling theunarginalportion of the upper in :si cl nanneras to p re'deterinine or regulate the io 'ination of wrinkles or pleats.The

construct-ion shown comprises membersv ior clamping the marginallp'orton of the upper upon the wipers'vwhile permitting the clamped portion toslip inwardlytowa rd the [01111 required in response to tensions arisinginthe upper as fit IS shapedoverthe term, the clamp members having intheir 13 a" er en a' iii' l aces a luralit of rooves J 5 ti t:

in which"wrinkles arepermittedi to form ,orn olding of the toe of as theitl'llllQSS' develops al a;ijriggfthe y combination, moreover, with themeans de-' scribed for gripping and holding the margin of the uppersubstantially at the ends of the tlp S8a.111, the means provided forlocalizing or regulating the formation of pleats in the .niargin of theupper contributes effectively to the general end in View, namely toafford accurate control of the position of the upper during the molding.

In the machine herein shown, as in the disclosure of the Letters Patentmentioned, the upper-shaping form receives a swinging movementrelatively to co-operating uppersh'aping instrumentalities during aportion of the shaping or molding operation while pressing the top orintermediate portion of the toe of the upper upon a toe rest or supportwhich yields in response to the pressure of the form. In accordance witha further feature of the invention the toe rest is mounted to swingabout the same axis as the form, thus insuring against any drag of thetoe reston'the top of the forepart of the upper in the moldingoperation. This construction is .also particularly useful where, asherein shown, the toe rest or support has a shape substantiallycomplementary to that part of the form whichis opposite thereto, sinceit insures against relative shifting of the twocomplementally shapedforming members.

The above and other features of the invention, incluc'lingalso novelmeans for applying wiping and holding pressure to the upper about theend and the sides of the form, novel means for detaching the moldedupper from the form, and various details of construction andcombinations of parts will now be more particularly described by 7reference to the accompanying drawings and thereafter pointed out'in theclaims.

Fig. 4 shows an upper mounted on a pie senter for use in presenting theupper to the machine; I t V Fig. 5 is a View in front elevation andpartly in section of the upper-molding instrumentalities, illustratinghow the upper is presented to the machine;

Fig. 6 is a view similar to Fig. 5 showing the partsin the positionsthatthey occupy at an intermediate point in the downward movement of theform; r

' Fig. 7 shows theparts as positioned when the wipers have substantiallycompleted their inward wiping movement; and

Fig. 8 shows theparts as positioned .while the upper is being held bythe wipers to substantially to the shape desired for thefinished shoe.The arm 4 is connected by an operating bar 8 and a rod 10-to a leverlQcontrolled by a roam (not shown) on a "camshaft 14, whereby downwardswinging movement is imparted positively to the form. 2 relatively tomeans for wipingthe upper upwardly about the end and the'sides of theform. At alater stage in the cycle reverse movement is imparted to'therod 10 to press the form upwardly against wipers which wipe the marginof the upper in]- wardly over the form, thus increasing the downwardpressure of the wipers'upon the marginal portion of the upper, a spring16 being inter'posed'betv'veen the end ofthe bar 8 and a collar on therod lO'to' render this pressure yielding.

The upwiping is effected by means of a toe band 18 which is in positionto embrace the end and the sides of the form 2' as the form isdepressed. The toe band 18 is 'controlled by mechanism more fully. shownand described in the prior Letters Patent, where' by it is advanced andclosed tobring it into operative wiping position and is also relit)tracted'and opened, this mechanisminclud- V inga bell-crank 20 (Fig. 1)connected by a link22 toa lever 24 provided with a'roll 25 which iscontrolled by a cam 26, more fully hereinafter described, onthe camshaftl4.

' Prior to the downward movement of the form the upper a is presentedto'the machine by the use of a'presenter 28(Fig. t) which isprovided'with upturned jig pins 30 for en- I gaging the'upper in jigholes formed in its margin substantially at the opposite ends of the tipscam 1), these ,jig pin's being arranged to enterslots 32 (Fig. 3)in'the wipers 15fto insure an accurately predetermined relation of'theupper to the molding instrumentalities. The toe of the upper is'thusoutspread substantially in a plane with'its margin over the top or outerfaces of the wipers. Before the form in its downward movement arrives inposition to engage the upper, the marginal marginal portion of theupper'inwardly over the form and, as herein shown, to .inold it inangular shapeagainst (Jo-operating faces'of the form to provi'de'aflange adapted forattachment to a welt shoe insole. As described inftheprior LettersPate'nt, the wipers are thus advanced and closed bymechanisinfincluding a toggle 38 'connectedby a linl; 40 to a lever l2operated by a camon't-he cam shaft 14.

Beneath-the form 2 is a toe rest or support 44 which, in theconstruction herein shown comprises a met-aljbloclr theupper' fa *e of jwhich has a contour substantiallycompie with theupper. a eompleinental1outer :form

' mined bya stopscrew 66 on'the casing mentalto that face of the formwhich is opo'site thereto and is preferably pr ivi-d ed with a leatherfacing 46 fer The toe rest thus serves as. and is shaped to engagesubstantially the whole of'thetop of'the forepart of the upperwhich-is'out of range of the wipingaction ofthe toe hand 18. The toerest 44in the'constr'ucti on herein shown is mounted upon the-upper endof a curved plunger 48 which is movablei-n a similarly curved guide/wayformed in a easing 50 supported onthe endof an arm'52.

The plungerLS is providedvwithraek teeth 5% in engagement with apinionet which is mounted on a spindle 58 n the casing 50, i

spindle lnving fastthereon a pair of lever arms 60 controlled byspr1ngs62 whic are connected respectively to said arms and to pins64-031 the casing, Itwill be seen that the springs positionoffthe restbeing adjustably det rengagementwith one of the arms 60. Pref erablfv'the toe rest will be positioned, as

shown, with its upper-engaging face about on a level w th the wipers15:. The toe rest a l is p votally mounted on the upper end of v theplunger 48 and may tip lengthwise of the form againsttho resistance ofcurved leaf sp'r i s 68 to permit it to bear evenly uppn the di erent,portions ofthe upper. It will be undei'stoodi that in the downwardmovement oft-he form 2 thefltop of the forepart of the upper is pressedupon "thetoo rest 44, and as the form continu'es its downward movementthetoerest is moved downwardly with it. he plunger 48'and-it-s guideway62 thus hold" ="tl1e toe rest 4% holes wn'iol'i are formed 'tl'ie-reiinand are curved in an arc the center of which is thesame as the axis 6about which the form 2 swings, so that there is no relative movementbetween the toe rest and the form after the upper has been clampedbetween these parts and, therefore, notendeney'to displace the upperr'elativly to the form by reason of any dragon the top of the forepa rt.

The clamp members 36 in the construction herein shown terminate at ashort'distanee from the tip line of the upper, and the machine isprovided withgrippers which grip.

the margin of the upper at and near the .endsof the tip seam beyond theends of the clamp members. Each" of' these grippers comprises 'a'pair ofaws 70 and 72, the

lower jaw 70 being faston a gripper bar 7 L whiehis secured at itsupper.end to an arm 76 pivo-tally m'ountedat 78 upon a bracket 80 onthe headof the machine, The 72 1s fast on a slide 82 which is guided for upwardand downward movements by a rib 84- on the'bar 17 i and has at its upperend head 86 provided witlr'a transverse groove 88. "In the groove 88 ismounted roll 90 which is carriedby an arm 92 fast ea s rock shaft 94. lilovementsof, the jaw 72 toward and from the jaw 70 are thus effected bythe rocking of the shaft 9%. The arm'TG at its outer end is engagedand'uplifted by a springQG the lower end of which is seated in asocketformed in a lug 98 on the bracket "80. The spring 96 thus servesto swing the gripper outwardly, and is yielclable' to per mit it toswing inwardly toward the form 2 in response to the pull of the upperthereon; To limit the outward swinging movement' of the gripperthe.-'arm 92 carries a limit stop comprising a plate 190 provided witharms of different lengths any oneof which may be moved into position'to"serve as an abutment" in engagement with the gripper bar '74. The plate100 is'secured to a ,irod" 102 which projects downwardly through the arm92 and has it its lower end an enlarged head 104 between which and theinnerend'of a'socket in thearm 102 is mounted a spring 106., By pressingup on the headloiand turning it the member 100 may bemoved to bring anyone of its arms opposite toithebar'i. -It is desired to position thegrippers with their aws close to the inner ends ofthe slots 82 in the*ipers, so that they w ll grip the upper adjacent to since the positionsof these slots will V as different wipers are substituted for dinents'iz'es or styles'of uppers, "he i'n'embz s 100 are utilized asdescribed to position its;

grippers in the proper relation to the diiiorent wipers. It will beobserved that the lower gripper jaw v7O is positioned close to the topv.facefof the wipers with only enough clearance to p re'ventinterference between the aw and the wipers as the arm is swung about itspivot 78. It will also be understood that the groove88 is so inclined asto permit the gripper to swing about the pivot 7 8 relatively to theroll 90 without any substantial effect upon the gripping pressure thatwhen the clamp member is moved downwardly toward the wipers it is alsoswung inwardly to bring it close to the edges of the wipers. Each arm108 is connected by a link 118, through ball-and-socket joints, to anarm 120 which is loosely mounted on the shaft 94. Secured adjustably tothe shaft 94 by means of a set screw'122 is an angular bracket member124 in one arm of which is an adjustable stop screw 126 which supportsthe arm 120. In the other arm of the bracket member 124 is adjustablymounted a screw 128 which bears on a spring plunger 130 in the arm 120.A yielding connection is thus afforded between each of the arms 120 andthe corresponding rock shaft 94 so that clamping pressure is appliedyieldingly.

to the upper by the clamp members. 36. It will also be evident that theforce of the clamping pressure applied by either of the clamp membersmay be varied by adjusting the corresponding screw 128.

The rock shafts 94 are provided at their rear ends with gear segments132 which are engaged lay-beveled gears 134 fast on short transverseshafts 136. The shafts 186 are connected by gearing 137 to a shaft 135provided with a lever arm 138 connectedby a link 140 to a lever 142which is pivoted at 144' on the frame of the machine and is providedwith a roll 146 engaged by a cam 148 on the shaft 14. A spring 150 isprovided for. moving the link 140 downwardly and thereby holding theroll 146 in engagement with the cam. It will be understood that when thelink 140 is moved upwardly by the cam the clainpinembers and thegrippers are operated to clamp and to grip the upper as above described,the clamp members heing operated yieldingly through the spring plungers130 while the grippers are closed positively upon the upper materialsThe force with which the upper is gripped by the gripper jaws 70 and 72may be varied, for example, by varying the length of thelink 140 througha turnbuckle 152, while the amount of resistance to the inward swingingmovements of the'grippers maybe varied by means of adjusting screws 154which determine the tensions of the springs 96.

By reference to Fig. 1 it will be seen that the cam 148 is so shapedthat upon the starting of the machine the clamp'members 36 and thegrippersare operated respectively to clamp the marginal portion of theupper upon the top of the wipers and to grip it at the ends of'the tipseam, and it will be understood that as the form 2 is moved downwardlythe grippers are swung in-. wardly toward the form in response totensions arising in the upper butin directions unaffected by thedirections of said tensions, while the clamp members permit 'the .7

portions of the upper engaged thereby to slip and move inwardlytowardthe form while applying thereto sufficient pressure to draw the uppertightly about theform. The

serrated gripping faces, so that they hold the upper from slipping asthe form is moved downwardly, and the opposite grippers 1n theconstruction shown are mounted to'swin'g directly toward each other sothat they hold the upper at the ends of the tipseam against any movementlengthwise of the form.

Substantially at that point in thevcycle when the wipers 15 begin theirinward wiping movement a slight declivity shown at 0 onthecain 148serves to relax the pressure of the clamp members 36 upon the upper andthus to permit it to slip more freely as it is gripper jaws 70 and 72are provided with 7 wiped inwardly over the form, althoughprevent anysubstantialdisplacement of the portionsat the ends of the tipseamlengthwise of the form, although the margin of the upper may slipsomewhat inwardly through the gripper jaws in response to'the pull ofthe wipers thereon. When the wipers have arrived approximately at theend of their operative movement, or in position to bend the margin ofthe upper over the edge of the form and thus secure a firm hold thereon,a further declivity d in the cam 148 causes the clamp members 86 to bewithdrawn to inoperativeposition and the grippers to open and releasethe upper.

In the construction herein shown the clamp members 36 have formed intheir generally plane upper-engaging faces a series of grooves 156 whichradiate outwardly from the form 2 and thus extend in substantially thesame directions as the lines of force or tension to which the differentrespective portions of themargin-of the upper are jected as the upper isshaped over the form. The grooves 156thusprovideispaces permitting theformation'of wrinkles or pleats in short of the inner edges of the clampmem bers 36, so that while the full clamping pressure is being appliedduringthe downward movement of the form the .clamp members by theirplane faces co-o'perate with the wipers in'laying the upper smoothlyabout the end'and the sides of the form. "\Vhen the clamping pressure isrelaxed at the beginning of, the inward movement of the wipers thewrinkles are permitted to form still more freely inthe grooves 156, andwhen the clamp, members are finally lifted t-hewrinldes or pleats extendin a regular series along that portion of the margin of the upper whichis to project upwardly from the bottom of the form and subsequently tobe trimmed.

The machine herein shownfis provided with means for controlling the toeband 18 in such manner as to increase the pressure of the band on theupper after the upwiping has been effected in response to the clownwardmovement of the form. As shown on Fig. 1 the cam 26 is provided with arise at e for this purpose, the increased pressure being yieldingly appled through the provision of a spring 158 forming a connection betweenthe link 22 and the bell-crank 20.

Additional insurance is thus afforded that the upper will be heldeffectively about the .endand the sides of the'form when the pressure ofthe clamp members 36 is relaxed at the beginning of the inward movementof the wipers. After the wipers have com pleted their inward movement adeclivity shown at f in the cam 26 causes the toe band 18 to withdrawfrom pressure applying rela tion to the upper in order to avoid anypossible danger of marking the upper during the time that the upper isheld by the wipers to permit it to set in moldedshape.

The machine is also provided with means' for detaching the molded toefrom the form 2. Extending lengthwise of the form isa spring plunger 160provided with an end portion 162 adapted to be projected forwardlyfromthe contour face of the end of the form. At its outer end theplunger 160 is arranged to beengaged by the end of an adjustable screw16 l'carried by alever 166 which is pivoted at 168 on the arm 4. At itsupper end the lever 166 is connected by a link 170 to a slide 172mounted in a guideway on the arm 4;. The slide 17 2 carries a roll 17%which is arranged to engage a cam face 17 6 on anarm 17 Ssecured to thehead of the machine. When the arm A is swung upwardly after the'mol'ding of the toe the cam face 176 actson the roll 17 1 and throughthe coi'inection's described forces the plunger 160 forwardly in theform to detach the molded toein case the toeshoul'd stick to the form.

In the operation of the machine, briefly summarized, the upper ismounted on the presenter 28, as illustrated in Fig. 4, and is 1presented tot-he machine in the manner illustrated in Fig. 5, the jigpins 30 of the presenter being moved to theinner ends of the slots 32 inthe wipers 15 and the marginal portion of the upper thus being outspreadover thetop face ofthe wipers with portions adjacent tothe jig pinsextending over the gripping jaws7O. Upon the starting of the machine theclamp members 36 are moved downwardly to clamp the upper upon the top ofthe wipers and the gripper jaws 72 are moved downwardly to grip theupper at the ends of the tip seam adjacent to the jig pins. After theupper has been thus clamped and gripped the operator, movement comesinto'engagement with the intermediate portion of the outspread upper andpresses it upon the toe rest or outer form member 44. "As the formcontinues its downward the upper is wiped upwardly about the end and'thesides of the form by the toe band 18 in the manner illustrated inFig. 6; During, the upwiping operation the marginal portion of the upperis permit-ted to slip inwardly toward the form between the clamp members36 and the wipers as required in responseto the pull thereon, thegrooves 156 in the clamp members localizing any wrinkles or pleats thattend to form at this time in response to the increasing fullness of themargin of the upper. At the same time the grippers, which hold the upperwith an unslipping grip, are swung inwardly against the resistance ofthe springs 96 in response to the pull of the upper thereon,thus prethepresenter 28 is removed by and the form 2 in its downward movement thetoe rest 1 1 is moved therewith about the same axis-and venting anydisplacement lengthwise of the I form of the portions of the upper atthe edge of the form and to mold an angularly shaped marginal flangethereon. During th1s'1nward movement of the wipers the clamp members 36permit the upper to slip more freely than in the upwiping operation,although continuing to hold the upper drawn tightly across the edges ofthe wipers, and the upper also may'slip inwardly to some extent betweenthe gripper jaws and 72, although the latter continue to hold the upperwith suli icient pressure to prevent undesirable displacement of itsmarginal portion lengthwise of the form. hen the wipers 15 have arrivedsubstantially or nearly at the end of their operative movement and havesecured an effective hold upon the upper by bending it over the edge ofthe form, asillustrated in Fig. 7, the clamp members 36 are raised torelease the upper completelyand the grippers are opened and are swungoutwardly by their. springs 96. After the wipers have completedtheiroperative movement the band 18 is opened to re lease the upper frompressure about the end and the sides ofthe form, as illustrated in Fig.8, the form being pressed upward yieldingly to increase the downwardpressure of the wipers on the upper. Thereafter the upper is held by thewipers for a sufficient time to permit itto set in molded shape, and inthe meantime the surplus margin of the flange on the upper projectingabove the bottom face of the form is trimmed oil by the operation oftrimming means such as described in the Letters Patent hereinbeforementioned. After the trimming operation the machine comes automaticallyto a stop, and when the operator starts it again the parts are returnedto starting positions, the form 2 being swung upwardly with the upperthereon. In the upward movement of the form the detaching mechanism isoperated by thecam face 176 to detach the upper from the form and permitit to be readily removed by the, operator.

While the invention is herein illustrated in its application to amachine particularly designed for molding the toes of welt shoe uppers,it is to be understood that the invention is not thus limited in itsapplicability;
